如何迭代并单击Instagram帖子Web元素列表-Selenium

Question

因此，目前，我正在尝试构建一个在Instagram上搜索特定主题标签的机器人，找到使用该主题标签发表帖子的每个用户，并向他们发送消息。

我能够从特定DIV中收集一个代表“标签”页面上的每个帖子的Web元素列表。现在，我的代码将遍历每个元素，试图单击页面上的每个帖子。

但是，为我点击的努力是如何在单击一篇文章后进入下一篇文章。

我当前的逻辑几乎只会遍历列表，然后重新单击该页面上的第一篇文章。以下是一些代码：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait       
from selenium.webdriver.common.by import By       
from selenium.webdriver.support import expected_conditions as EC
import time, urllib.request
import requests
from dotenv import load_dotenv
import sys
import os

# get prod.env vars
sys.path.insert(0, os.environ['HOME'])

dotenv_path = os.environ['HOME'] + '/prod.env'

load_dotenv(dotenv_path, override=True)    
locals().update(os.environ)

# Search up hashtags
PATH = "/Users/Nick/Desktop/chromedriver"

# headless options
# op = webdriver.ChromeOptions()
# op.add_argument('headless')

driver = webdriver.Chrome(executable_path=PATH)
ig = driver.get("https://www.instagram.com/")
time.sleep(5)

# username and password input
username=driver.find_element_by_css_selector("input[name='username']")
password=driver.find_element_by_css_selector("input[name='password']")
username.clear()
password.clear()
username.send_keys(ig_user)
password.send_keys(ig_pass)
driver.find_element_by_css_selector("button[type='submit']").click()
time.sleep(10)

# take care of popups
notnow = driver.find_element_by_xpath("//button[contains(text(), 'Not Now')]").click()
time.sleep(10)
notnow2 = driver.find_element_by_xpath("//button[contains(text(), 'Not Now')]").click()
time.sleep(5)

# # search hashtag
query = "goodproblems"
page = driver.get("https://www.instagram.com/explore/tags/" + query)
time.sleep(5)

# driver.find_element_by_class_name('_9AhH0')
post_divs = [elem for elem in driver.find_elements_by_class_name('_9AhH0')]

for post in post_divs:
    time.sleep(2)
    the_post = driver.find_element_by_xpath("//*[@id='react-root']/section/main/article/div[1]/div/div/div[1]/div[1]/a/div/div[2]").click()
    time.sleep(4)
    name = driver.find_element_by_xpath("/html/body/div[6]/div[3]/div/article/div/div[2]/div/div/div[2]/div[1]/ul/div/li/div/div/div[2]/h2/div/span/a").click()
    time.sleep(3)

    try:
        message = driver.find_element_by_css_selector("button[type='button']").click()
        time.sleep(2)
        driver.back()
        # cancel = driver.find_element_by_xpath("/html/body/div[6]/div/div/div/div/button[5]").click()
        driver.back()
        driver.back()
        time.sleep(4)
       
        # message_input= driver.find_element_by_xpath("//*[@id='react-root']/section/div/div[2]/div/div/div[2]/div[2]/div/div[2]/div/div/div[2]/textarea").send_keys("Sample message")
    except:
        print("no message button")
        # cancel = driver.find_element_by_xpath("/html/body/div[6]/div/div/div/div/button[5]").click()
        driver.back()
        driver.back()
        driver.back()
        # cancel = driver.find_element_by_xpath("/html/body/div[6]/div/div/div/div/button[5]").click()

        time.sleep(4)
